LANDAULET.

Application filed May 2'7, 1916.

To all whom it may concern:

Be it known that I, JOHN T. ALLMAND, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan,

. have invented a certain new and useful Improvement in Landaulets, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to landaulets. Heretofore considerable trouble has been GX- pericnced in swinging the movable roof sec tion of the landaulet forward on to the permanent roof section. Cramping of the supporting mechanism at one side or the other is frequently experienced and very often it requires two persons in order to swing the movable roof section over to the permanent roof section.

It is to obviate this difiiculty and afford a landaulet with a movable roof section which easily swings over on to thepermanent roof section that this invention is designed. 7 a

In the drawings,-

Figure 1 is a side elevation of that portion of the landaulet to which my invention is applicable.

Fig. 2 is a fragmentary top or plan vlew of such portion.

Fig. 3 is a view similar to Fig. 1 but showing the landaulet opened up.

Fig. 4 is asection taken on the line AA of Figs. 1 and 2.

Fig. 5 is an elevation of the toggle tightening device.

Fig. 6 is a longitudinal section of the same. r

Fig. 7 is a similar view showing the action of the toggle tightening device when comparing this figure with Fig. 6.

Fig. 8 is an enlarged detail of the hinge.

Fig. 9 is a side elevation of the landaulet showing how the swinging roof section is swung over on the permanent roof section.

In the drawings, a indicates the forward permanent section of the landaulet which is provided with the usual door 5 carrying a sliding slab of glass 0 which can be dropped into the window well d in the bottom of the door in the customary way. The rear section is made up'of a movable Specification of Letters Patent.

roof portion 6 which includes the upper horizontal rails of the rear window frames and the collapsible rear portion f, which includes the side uprights g of the rear window frames. These side uprights are hinged to the body proper by the iron fixtures h which are also provided with lugs which pivot the telescoping braces i that serve as oblique supports between the upper portion of the side uprights and the body proper when the rear section is in closed position. The flexible fabric which serves as a covering for the rear portion of the rear section of the land-aulet is not shown in Fig. 8.

The movable top portion of the rear section can be easily swung out to disengage the dowel pins in and swung forward to dispose it out of the way on the permanent roof section. This is accomplished by reason of the peculiarly constructed hinges now to be described. These are designated Z and are made up of two strips 777. and n which are the short strips and which are secured respectively to the roof of the permanent top and the movable roof portion of the rear section. Between these two strips are two more strips," one of which is a long strip and the other a short strip, which are each pivoted to one of the strips m and n and which are pivoted to each other. These form a compound link 0. The two members of this compound link 0 are each provided with abutting stops 3 (see Fig. 8) so the compound link can break in only one direction, namely, downward. The short link of the compound link 0 is provided with a stop as which likewise prevents this joint from breaking upward or outward except as already alluded to, namely, to the small extent necessary to allow the dowel pins k to withdraw from the dowel holes as shown in Fig. 9.

The action of this triple jointed hinge is as follows: The movable roof portion of the rear section after the rear collapsible portion has been disengaged, is tilted slightly, as shown in Fig. 9, thereby allowing the shallow dowel pins to withdraw from the dowel holes. The stops 00 and 3/, 1 now prevent the two joint arms at the right of the hinge from breaking upwardly or outwardly toward each other and consequently the movable roof portion swings on the hingeparts which pivot at the point a, Fig. 9. When the swinging hinge parts the long strip of the compound link 0 and prevents further inward movement of the short strip of the compound link with respect to the long strip of the compound link. This makes surethe movablesection always taking up the same position on the permanent roof so as to make the'locking deviceparts hereinafter to be referred to, register. It also makes sure of theproper positioning of the movable section with respect to the linkage so'that when it is desired-to again draw the movable roof portion over to its positionof service, no unusual-effort is required to start it.

It will be noted that a rubber bumper o is employed to prevent the strip m and the long strip of the compound link from clashing.

Thistriple jointed hinge, of which there will usually be two, affords a very easy way Oflifting the movable roof'portion over on to, the permanent section without any chance of cramping, and it will be found that one person can easily effect this movement with out any other aid, which has usually been impossible with the constructions heretofore used for this purpose. 7

This rigid roof portion may beclamped to the permanent roof 'so that it will not rattle; by means of the tightening device shown, in Figs. 5, '6 and 7 which comprises merely a pair of loops adapted to engage over {the hooks on the movable rigid roof portion and the permanent roof portion and be drawn towardeach other to shorten the clamp by means of the lever g which is connected with the two loops on the toggle principle.-

Before or after the rear collapsible portion has been collapsed and the rigid roof portion has been swung over onthe permanent section the slabs of glass can be dropped out of sight in the window wells or pocketswhich are ordinarily provided in the body proper. This is shown in Fig. 3'.

7 What I claim is:

'1. In a landaulet, the combination of a permanent front section, an openable rear section, the latter including a movable roof portion immediately adjacent the permanent front section, and a triple jointed strap having one end secured to the roof of the permanent section remote from the rear edge of the front section and the other end; secured to the movable roof portion of the rear section for. allowing. the said movable roofjportion of the rear section to .bQ-SWIJIIg ever" onto :the permanent roof.

2. In a landaulet, the combination of a permanent front section and an openable rear section, the latter comprising a movable roof portion immediately adjacent the permanent front section, and a triple jointed strap comprising a pair of straps one secured to the top of the said movable roof section remote from the rear edge of the front section andthe other secured to the permanent roof, and a compound link con- 7 necting the two straps adapted to allow the of the compound link with the strip secured to the movable roof section being arranged to avoid any substantial breaking ofthe joints by relative movement of the links and movable roof section strip upwardly toward each other.

4:- In a landaulet, the combination of a permanent roof section, an openable rear section, the latter comprising a movable roof section interlocking with the front section by dowel pins and dowel holes, and a triple jointed strap comprisinga pair of strips, one joined to the top of the movable roof section and the other to the permanent roof, a compound linkconnecting the two strips provided-with a pair of stops on its individual link members to abut and prevent breaking of the jointby relatii e movement of the links upwardly toward each other and provided with a stop on the individual link joining the strip connected with the movable roof: section, which latter stop is slightly spaced from the strip attached to the movable roof' section. when that section isin position for service for the purpose ofallowing a limitedswing of the movable roof section at this joint to withdraw the lowel pins from the dowel holes but avoiding breaking of the joint beyond thislimited are by relative approaching upward movement of the joint members.

5. In a landaulet, the combination of a permanent front section, an openable rear section, the latter including a movable roof portion and a triple jointed strap, comprising a pair of strips, one secured to the top of said movable roof section and the other secured to the permanent roof, a compound link connecting the two strips adapted to allow the movable roof portion to swing ever on to 'the permanent top, stops for preventing any substantial upward and outward movement between the strips at the joint of the compound link and the strip secured to the movable roof portion and the joint between the individual strips of the compound link, and a stop for preventing inward and downward swing between the two individual links of the compound link beyond a substantially perpendicular rela tion for the purpose set forth.

6. In a landaulet, the combination of a permanent front section, an openable rear section, the latter including a movable roof section, and a triple jointed strap comprising a pair of strips, one secured to the top of the movable roof portion and the other secured to the permanent roof, a compound link connecting the two strips adapted to allow the movable roof section to swing over on to the permanent top, stops on the strips for requiring the movable roof section to always take up a specified position on the permanent top, and locking means on the movable top and permanent top, the parts of which are assured registry by the said means on the said strips.

7. In a landaulet, permanent and movable roof sections immediately adjacent each other, strips secured to the front end of the movable section and to the permanent section at a point remote from the rear edge,

and a compound link connecting these strips provided with a stop w which prevents the link parts breaking in one direction beyond substantially a perpendicular relation.

8. In a landaulet, permanent and movable roof sections immediately adjacent each other, strips secured one to the front end of the movable section and the other to the permanent section at a point remote from the rear edge, and a compound link connecting these strips and provided with means for preventing the link portions breaking upwardly toward each other and also provided with means for preventing the links breaking downwardly toward each other beyond substantially a perpendicular relation.

9. In a landaulet, the combination of a permanent front section, an openable rear section, the latter comprising a movable roof portion immediately adjacent the front section and a strap hinge having portions secured to the movable roof section and to the permanent front section remote from the rear edge and arranged to allow the movable section to move bodily and without inversion over upon the permanent roof section.

In testimony whereof, I sign this specification.
